I have a csv list of values i want to use to change the Bevel modifier amount for a collection of a big number of cubes. I don't really know Python but tried something based on things I found in youtube, as follows:

import csv
import bpy

bar_spacing = 1.5
bar_width = 1

with open ('C:/Users/USER/Downloads/HD1.csv') as f:
    readout = list(csv.reader(f))

for a in readout:
    placement = readout.index (a)
    bpy.ops.mesh.primitive_cube_add(size=1)
    bpy.ops.object.modifier_add(type='BEVEL')
    new_bar = bpy.context.object
    
    for vert in new_bar.data.vertices:
        vert.co[1] += 0.5
        vert.co[0] += placement*bar_spacing + 0.5
        
        new_bar.'bevel' amount = (bar.'bevel' amount, float (a[1])

I took the example from this video on how to create data visualization modifying bar sizes, and tried to alter it. The next picture is what I want to achieve, but with the complete set of 1080 diferent cubes: to have their own bevel amount value from the data, as in the next image:

example of the intended result

And example of the value/table,

UPDATE! With @cod3R help, I managed to get every cube with it's specific Bevel from the data. Now a new problem: How to distribute them into rows? This is how it looks now and the code i used:

enter image description here

loc_y = 0.0

Use the low-level function to add modifiers which allows for direct property access: https://docs.blender.org/api/current/bpy.types.ObjectModifiers.html#bpy.types.ObjectModifiers.new

import bpy

# Get the object
obj = bpy.context.scene.objects['Cube']

# Add the modifier the low level function and set the bevel amount
bevel_mod = obj.modifiers.new(name="MY-Bevel", type='BEVEL')
bevel_mod.width = 0.01

########################################################

One simple loop to add cubes based on the data should do:

import bpy

loc_y = 0.0
for data in (1.0, 0.5, 0.25, 0.1, 0.01):
    # Add the cube to the scene and get it
    bpy.ops.mesh.primitive_cube_add(location=(0.0, loc_y, 0.0))
    cube = bpy.context.object
    # Add the bevel modifier
    bevel_mod = cube.modifiers.new(name="MY-Bevel", type='BEVEL')
    bevel_mod.width = data
    # Offset the initial location
    loc_y += 3.0

enter image description here

EDIT Setting up the rows is also fairly simple:

import bpy

bevel_amounts = [1.0, 0.5, 0.25, 0.1, 0.01]
loc_x = 0.0
loc_y = 0.0
offset = 3.0
items_row = 7

for i, data in enumerate(bevel_amounts, start=1):
    # Add the cube to the scene and get it
    bpy.ops.mesh.primitive_cube_add(location=(loc_x, loc_y, 0.0))
    cube = bpy.context.object
    # Add the bevel modifier
    bevel_mod = cube.modifiers.new(name="MY-Bevel", type='BEVEL')
    bevel_mod.width = data
    # Offset the initial location
    loc_y += offset
    # Add a new row 
    if i % items_row == 0:
        loc_x += offset
        # Reset y
        loc_y = 0.0

  • $\begingroup$ Thank you! that worked perfectly. I've updated the question with a new (smaller) question. I now have the correct cubes with their specific bevel. How can I distribute them into rows (say, 7 cubes per raw)? $\endgroup$ Commented Jan 2, 2022 at 21:02
